Seems they're not very rugged. I searched the archives (Zenith list) and found someone discovered the ones Zenith supplied with flap actuators are no longer made, but there is a replacement unit. They're also made by Honeywell, rated at 15 amps. The replacement is actually a two-parter. The microswitch and the roller/lever arm. The switch is about $8 and change and the roller/lever is about $11 and change from www.gopherelectronics.com. (There are a million part numbers for microswitches.) The mounting holes are not of the same pattern as the old ones. I don't have the part numbers handy but can get them for you in a couple days if you can't find the post in the archives. The reason I ordered one is because I want to use two on the down-travel side. If there is only one, and it fails, and the pilot relies on that switch to shut off the flap motor at full deflection, the flaperon bellcranks poke holes in the bottom skin, and you get who knows how many degrees of flaps--maybe enough to be catastrophic. So I'm using two switches wired in series so if either one or both work, the circuit is opened. On the up-travel end, there is a crow-bar terminal to stop any override in case of a failed microswitch. (Speaking of the -801.)

That is what I suspected. Now the other question, for those who have done this, do I the builder sign off Phase 1 based upon my test pilot's reports or does the pilot himself sign the log book? I can find CFIs all over the place willing to solo me , so long as it is not Phase 1, once I get my US medical in June of 2009. I have a feeling we will have enough information on the airframe by 6/3/09 for my CFI to make an educated decision. Good news for my continued test flights... originally the FAA had three proposals to extend class bravo for OHare, one basically took my test area away, one had the "Sabrina notch" for KARR and one took just 1/3 of a mile away from my Eastern edge (which was too populated anyhow.) The later seems to be the one the FAA is going with. Thank you FAA!

With the election of our new President you can expect several new and ever changing TFRs in the Chicago area. While we won't be surprised to see you in the news in the future. We don't want to see your plane being escorted by black helicopters and F-16s. As far as signing off for the 40 hours I think that would be a very good question for the EAA. -------- W.R.

I do not know if it was for insurance reasons or what, but it was very specific on the plane and it was for 90 days. Even now that I have my license, I have to get checked out in any other type of plane that I want to rent. That I am sure is for insurance reasons.

Craig, My aircraft has been sitting outside for 12 months now at KARR. The Viton o ring is rated at -8C where as Nitrile is rated at -25C. (Viton can withstand +204 C compared to +121C but what good is that for a fuel cap seal.) At KARR, we can easily get below -8C several times a year. The Viton is twice as hard and has only 60% of the tensile strength. So too, it is 10X the price. I decided to switch to Nitrile o rings after last Fridays flight. On take off, beyond the go/no go point on 18 (a short runway, 9/27 is closed) the sealing lever of the right cap popped upthe plane was just refueled and the o ring must have not seated properly. Immediately the fuel pressure dropped on the right pump and the Dynon sounded an alarmapparently the Facet pump could not overcome the draw out of the tank. This was the first alarm during 10 months of test flights. The tower noticed the contrail and asked if assistance was required. In just one left circuit two gallons were sucked out. The cap remained in place but not sealed. The pilot turned off the external lighting, informed the tower he had one good tank and pump and landed without incident. My pilot was surprised that the overflow tube/vent did not prevent the fuel from being sucked outit probably helped but was not large enough. Upon ground inspection, the overflow vent was clear and the o-ring was loose compared to the o-ring on the left tank cap. The viton o-rings will be replaced tomorrow. An engineer who was kind enough to review the problem said I would have been better off loosing the entire cap, with such a large opening the fuel would not have been sucked out as easily as it was with a slightly raised seal. I don't know if he is correct, but I have heard stories of C150s taking off and hearing a clang, clang for a while before the fuel cap rips off. They seem to have made it to their destination unaware.

If you send me some, I'll take it to work and do some analysis that might tell you what caused the corrosion. I'd be able to tell if it was biological, humidity, or caused by something else. I'm a materials engineer and so I have access to all kinds of analysis equipment at work. No guarantee I'll find a solid answer, but my time and effort is free so all you have to loose is a piece of corroded aluminum!

I screwed up on my first order (I know none of you have ever done that) and an RMA was immediately issued, with shipping credit!! I'm a VERY happy camper, and highly recommend these people.

If you do, would you be willing to cut a piece of the worst-looking stuff and send it to me?? Something the size of a business card or so would be plenty.? If you send me some, I'll take it to work and do some analysis that might tell you what caused the corrosion.? I'd be able to tell if it was biological, humidity, or caused by something else.? I'm a materials engineer and so I have access to all kinds of analysis equipment at work.? No guarantee I'll find a solid answer, but my time and effort is free so all you have to loose is a piece of corroded aluminum!? I'm storing some parts in my basement, some in the living room, and some in the garage.? I've been curious about corrosion during storage and so you're problem could provide some good evidence.

Roger _____ From: owner-zenith-list-server@matronics.com [mailto:owner-zenith-list-server@matronics.com] On Behalf Of crvsecretary@aol.com Sent: Wednesday, November 05, 2008 3:02 PM Subject: Zenith-List: Carburetor Hello Bobby: Although I am FAR from an expert on Bing CV (constant velocity) carbs, i can attempt to explain the theory of what is happening.... At idle you are running exclusively through the idle circuit. As you crack open the throttle, there are transition circuits that come into play. When you get to 1500 you are running "on the needle" that sticks through the main jet, efffectively closing off the size of the main jet fuel flow until the needle retracts....from 3/4 throttle to wide open you're on the main jet only. Transition circuit problems are very difficult to diagnose. Sounds like you are running very rich through this circuit. I would recommend a note to Jabiru USA - Pete knows these things better than anyone. The other source of information is "The Carb Doctor" http://www.bingcarburetor.com/ who is the official importer of Bing carbs and parts here in the USA. The manual is worth every penny. It's been a long time since I had to access this info, but every owner of an old BMW "airhead" motorcycle has had to deal with these carbs at least once !! After some thought...check your float height. If it is set too high that would cause a rich running engine.....

I am laying out the rivet lines for my 601XL ailerons. The rivet line through the top skin into the front skin flange and top rib flanges is positioned at 10mm from the front of the skin (midway on the 20mm front flange). According to my measurements, these rivets will not meet the minimum edge distance requirements from the front of the rib flanges, because the way the ribs are manufactured, there is about a 4mm to 5mm gap between the front rib flange and the start of the top flange. So with the thickness of the front skin figured in, my edge distance from the front edge of the rib flanges will only be about 4mm. I can't come up with a way to meet the minimum - all I could do is add another rivet, but the plans just show a normal pitch 40 on the remaining rivets. Does anyone know if this is an issue, or is it acceptable for this particular edge distance not to meet the minimum? I know when I built my stabilizer, there was a specific note that said I did not need to worry about this end-of-rib-flange edge distance, but I don't want to assume that it applies in all cases. Any help would be appreciated.

And jabiru=92s motors In the past, on the 2200 jab of a friend , we were confronted to the same problem you talk about. As you said Tracy, problem was coming from the position of the floats. When you hold the carburetor upside down, the level of the float must be absolutely parallel to the edge of the carburetor . You can correct this easily by bending smoothly the little piece of metal that will control needle movement. If your motor is brand new, check also if your needle is really clean .. we also have had problems with extra small parts of rubber coming from fuel hooses, Stuck by temperature and impeaching good movements . No way to see it at first sight .. and too small parts for the filter =85! Good luck ! Francois ________________________________ Message 30 ____________________________________ Time: 08:29:55 PM PST US Subject: Zenith-List: Re: New engine mount now ready to ship From: "Sabrina" I have been flying 5 years and 10 months now. And let me tell you, the flight instructors in Canada let you fly, especially when it is your equipment and not theirs. You actually have full spin training (three revolutions before they give you the controls) and off field emergency landing practice (wheels touching the grass) before any solo. Since I already soloed on my 14th birthday 13 hours before my birth hour, I really see no need to solo on my 16th birthday. My medical examiner for Canada lives in Florida, he can also issue U.S medicals. I figure I will go to Disney World for free on my birthday and get my medical the next day. A sponsor has suggested that I fly their Inspiration 2 for CNN but Juan was complaining about it vibrating and a terrible rate of climb: "400 fpm on the 0-200 at 70 mph climb out, versus 3300 went up at 1100 fpm at 70 mph with two aboard at climb out. much less vibration than the 0-200" So too, others have suggested I solo in an RV-12 as part of a movie a cool NYC producer is putting together about homebuilding--as you may have heard, part of the movie was filmed at Air Venture 2008. The great thing about both Zenith and RV is they are both supportive of whichever decision I make--they both want what is best for me. Really cool. My aircraft with an O-200a has less vibration than any 3300 my test pilot has flown and nearly triple I2's 400 fpm climb rate even at 1300 pounds on a hot, humid August day. To please both ZENITH and RV, I might just wait until I get back to Chicago in mid-June, get my driver's license first, drive to the airport, sign the SABRINA out of Phase 1, complete a CFI check ride, get the required signature and solo with no cameras, no nothing. (OK, maybe an on-board camera.) You guys are the best... I would not be where I am without all of you.
